78P2344JAT  
4-port E3/DS3/STS-1 LIU  
with Jitter Attenuator  
DATA SHEET  
JULY 2005  
DESCRIPTION  
The 78P2344JAT is  
FEATURES  
•
Transmit and receive interfaces for E3, DS3 and  
STS-1 applications  
a
low-power, 4-port  
DS3/E3/STS1 Line Interface Unit (LIU) with  
integrated Jitter Attenuator (JAT). It includes all the  
required clock recovery and transmitter pulse  
shaping functions for applications using 75-ohm  
coaxial cable at distances up to 1350 feet. These  
applications include DSLAMs, T1,3/E1,3 digital  
multiplexers, SONET Add/Drop multiplexers, PDH  
equipment, DS3 to Fiber optic and microwave  
modems and ATM WAN access for routers and  
switches.  
•
Designed for use with 75 ohm coaxial cable  
lengths up to 1350 ft  
•
•
•
Receives DS3-high and DSX3 monitor signals  
Local and Remote loopbacks  
Selectable B3ZS/HDB3 ENDEC with line code  
violation detector  
•
•
Standards-based LOS detector  
Optional serial-port based mode selection and  
channel status monitoring  
•
•
•
Adaptive digital clock recovery (uses line-rate  
reference clock input)  
Receive output clock maintains nominal line-rate  
frequency at all times  
Fully integrated Jitter Attenuation function  
provided for all line rates (no external VCXO  
required)  
Jitter Attenuator configurable for transmit or  
receive path  
Transmit line fault monitor  
Requires no external current-setting resistor or  
loop filter components  
Single 3.3V supply operation  
Available in 100-pin Exposed Pad JEDEC LQFP  
The receiver recovers clock and data from a B3ZS  
or HDB3 coded AMI signal. It can compensate for  
over 12dB of cable and 6dB of flat loss. The  
transmitter generates a signal that meets the  
standard pulse shape requirements.  
The  
78P2344JAT includes optional B3ZS/HDB3 ENDEC  
with a receive line code violation detector, loop-back  
modes, Loss of Signal detector, clock polarity  
selection, and the ability to receive a DSX3 monitor  
signal.
